SHIFTING TIME

Active Debris Remover (Patented ADR technology)
Patented ADR technology is a patent-pending technical feature that is based on a unique combination that makes it virtually impossible for debris to enter the bearing.

It consists of a new dust cover design that sits safely anchored in a groove in the pulley wheel, thereby completely enclosing the bearing. This is paired with a bladed groove structure that surrounds the dust cover, which dynamically extracts debris from the pulley wheel when it's rotating.

ADR has been developed in a constant pendulum between our R&D department, the CeramicSpeed test lab, and field testing conducted by a select group of our professional off-road teams.

ALPHA Disc
For our new OSPW RS, we're offering versions fitted with the ultra-durable ALPHA Disc Pulley Wheel first introduced with our OSPW X for Eagle Transmission.

The ALPHA Disc features a two-piece construction. A separate narrow-wide tooth profile produced in a composite material that offers prolonged wear protection and noise reduction. As well as a solid aluminum disc that eliminates the potential of external objects getting stuck between the spokes of the pulley wheel, while adding strength and stiffness to the Pulley Wheel design.

The first iterations of our solid disc pulley wheel design were tested in the field during the 2022 CycloCross World Cup season, which provided valuable feedback on its ability to provide mud clearance in the worst of conditions.
